Pattern based CAPTCHA for user authentication

Problem statement:


•"Text based CAPTCHAS" is a good way to authenticate between the human and machine, but with the development of automated computer vision techniques, which are designed to remove noise and divide the text to make characters readable for OCR, this makes text-based CAPTCHA is not considered safe anymore for authentication.
